Description

Technical Field

[0001] This invention relates to the field of vehicle display technology, and more particularly to a quality inspection device for vehicle display screens. Background Technology

[0002] In-vehicle displays are typically LCD screens with external speakers, SD card readability, USB connectivity, and Bluetooth. They often feature caller ID announcements. This is because LCD screens are relatively small and easy to install; they can be mounted near the dashboard, on the roof, behind seats, or even on the sun visor, making them convenient for use in various situations. Quality testing is required during the manufacturing process to ensure a high pass rate for all in-vehicle displays leaving the factory.

[0003] Current testing methods for in-vehicle displays only perform simple tests on their interfaces and functions, and manually reject any defective displays. They fail to test the displays in real-world usage scenarios, such as image distortion, color difference, and reflected light interference under different viewing angles and lighting conditions. This results in factory-made in-vehicle displays failing to guarantee a good user experience for drivers. Furthermore, existing testing equipment cannot simulate the operation of in-vehicle displays installed in cars, such as testing their stability under different road conditions and temperature environments. This limitation restricts the comprehensive testing of in-vehicle displays, affecting the quality of the testing process. To address these issues, we propose a quality inspection device for in-vehicle displays. Summary of the Invention

An interface detection mechanism checks the interface connections of the display screen. A power supply mechanism provides power for the testing operation. When the display screen moves under a sealing mechanism, the sealing mechanism seals and blocks this area to prevent interference from external light sources. An adjustable supplementary light illuminates the display screen, simulating scenarios such as natural light, strong tunnel light, and low-light conditions at night. This is achieved through an adjustment mechanism, an optical detection mechanism, and... The flipping mechanism allows for comprehensive adjustment of the position and shooting angle of the high-precision camera. The high-precision camera captures real-time distortion, color difference, and reflected light interference from the vehicle display screen.

The rotation of the rotating disk moves multiple vehicle display screens to the bottom of each detection mechanism, realizing high-precision positioning and transportation of the vehicle display screens. The modular structure facilitates positioning and support for vehicle display screens of different specifications. Attached Figure Description

[0030] Working Principle: During use, the operation of the control device is controlled via the control panel 110. A positioning seat 250 matching the shape of the vehicle-mounted display screen is selected and bolted onto the rotating disk 240. The positioning seat 250 provides adaptive positioning and support for the vehicle-mounted display screen. A stepper motor 220 drives the drive shaft A230 to rotate stepwise. The rotation of the drive shaft A230 drives the rotating disk 240 to rotate, moving multiple vehicle-mounted display screens to below various testing mechanisms, achieving high-precision positioning and transfer of the display screens. A conveyor 330 transports the display screens before and after testing. This system can interface with external production lines for automated testing of the vehicle-mounted display screens. The drive motor A430 drives the lead screw... Rotation of screw A431 causes sliding block A440 to move, which in turn moves vacuum suction cup 460. This allows vacuum suction cup 460 to be moved above positioning seat 250 and conveyor 330. Electric telescopic rod A450 moves connecting frame 451 up and down, further moving vacuum suction cup 460. Vacuum suction cup 460 then grips and holds the vehicle-mounted display screen, allowing it to be transported to the testing device and then to the transport mechanism, thus automating the loading and unloading of the display screen. Cylinder A520 moves drive plate A521, causing testing plug 530 to insert into the interface of the vehicle-mounted display screen. Interface testing instrument 540 then tests the display screen... The interface connection is checked. During the test, cylinder B620 moves drive board B621, which in turn moves power plug 630 into the vehicle display screen's power supply interface, enabling power supply to the display screen. When the display screen moves below the sealing mechanism, hydraulic rod A720 moves connecting bracket 721 downwards, which in turn moves sealing cover 730 downwards. Sealing cover 730 presses against the area around the display screen below, sealing and shielding that area to prevent interference from external light sources. Adjustable supplementary light 740 illuminates the display screen, simulating scenarios such as natural light, tunnel strong light, and low light at night. Drive motor B820 drives... The rotating lead screw B821 causes the sliding seat B830 to move up and down, which in turn moves the optical inspection mechanism up and down, allowing adjustment of the distance between the high-precision camera 950 and the vehicle display screen. The drive motor C850 drives the lead screw C851 to rotate, which in turn moves the sliding seat C860 laterally, allowing adjustment of the lateral position of the high-precision camera 950. The servo motor 930 drives the drive shaft B931 to rotate, which in turn rotates the rotating seat 940, causing the high-precision camera 950 to rotate, allowing adjustment of the lateral shooting angle of the high-precision camera 950. The reduction motor 1020 drives the drive shaft C1021 to rotate.The drive shaft C1021 rotates, causing the drive arm 1030 to swing at a certain angle. The drive arm 1030, through the connecting column 1040 and the connecting seat 1050, drives the adjustment mechanism to move, which in turn drives the optical detection mechanism to move. This allows for angle adjustment of the longitudinal shooting angle of the high-precision camera 950 towards the vehicle display screen, simulating different driver perspectives. The high-precision camera 950 captures distortion, color difference, and reflected light interference of the vehicle display screen image in real time, and, in conjunction with the adjustable fill light 740, adjusts the light source environment. This quantifies the reflectivity and visibility of the vehicle display screen under different lighting conditions, improving the driver's user experience when the vehicle display screen leaves the factory. The drive motor D1130 drives the lead screw D1131 to rotate, which in turn drives the sliding seat D1140 to move, thereby causing the touch head 1181 to move laterally. The drive motor E1160 drives the lead screw E1161 to rotate, which in turn drives the sliding seat D1140 to move laterally. The seat E1170 moves, thereby causing the touch head 1181 to move longitudinally. Cylinder C1180 then moves the touch head 1181 up and down, allowing for multi-point touch detection of the vehicle display screen. During this process, heating lamp 1191 heats the display screen, simulating its stability under different temperature conditions. Hydraulic rod B1220 moves the mounting plate 1230 upwards, which in turn moves the support column 1240, lifting and supporting the display screen. Hydraulic rod C1260 moves the connecting buffer plate 1261 and positioning groove 1270 downwards, pressing and positioning the display screen. Vibrator 1280 vibrates the positioning groove 1270, causing the display screen to vibrate, simulating the bumps and vibrations of a moving car and testing its stability under different road conditions.
